in a continuous system, the pressure is 3 mbar. this pressure is produced by using an ejector at the end of the pipe line. in the middle of the process there is a tank which has liquid and vapor phases. I want to make sure that no liquid would enter the vacuum pipe. Is there any method to calculate the minimum height of the tank? the tank is a cylinder with the volume V.
Hossein Porhimati,
Conversion of vacuum into Head in meter and density of the condensed liquid is required,
e.g. Pressure =3 mbar=0.001 bar
Absolute Pressure = 0.0010197 kg/cm2a
Density of the condensed liquid = 980 kg/m3(you can take as per fluid used)
Gauge Pressure = 0.0010197-1.03 kg/cm2g =-1.0289 kg/cm2g
Minimum Height = Gauge Pressure/Density of the liquid
Minimum Height = -1.0289 X 104/980 m
Minimum Height =-10.499 meter(minus sign shows the distance below condenser)
Please find attached herewith excel sheet Calculator
Good Luck!
